The invention provides a prefabricated pile mold. Bumps are arranged in a mold cavity of the mold at intervals in the axial direction, so that concave areas and convex areas which are alternately distributed in the axial direction are formed in the mold cavity; at least one convex rib in the axial direction is arranged in each concave area; at least one groove in the axial direction is formed in each convex area, and at most one end of any groove penetrates through the corresponding convex area; each concave area communicates with one end of the groove in the convex area adjacent to the concave area; a drawing chamfer is arranged on the periphery of each groove; and the width of each groove is reduced along with increase of the radial direction, and the cross sectional area of each groove is in a trapezoid shape. According to the prefabricated pile mold and the prefabricated pipe pile produced by the same, the surface area of a pile body of the produced prefabricated pile is increased, so that the frictional resistance with soil is further increased, and the bearing capacity of the prefabricated pile is improved.
本发明提供了一种预制桩模具，所述模具的模腔内沿轴向间隔设有凸块，使模腔内形成沿轴向交替分布的凹陷区和凸起区；所述凹陷区内至少设有1个沿轴向的凸肋，所述凸起区内至少设有1个沿轴向的凹槽，且任一所述凹槽最多一端贯穿凸起区。所述凹陷区与其相邻的凸起区内的凹槽一端连通。所述凹槽周边设有起模倒角，且所述凹槽的宽度沿径向增加而变窄，所述凹槽的横截面积为梯形。本发明生产预制桩桩身的表面积增大，从而进一步增大了与泥土的摩阻力，提高了预制桩的承载力。
